Did a US Navy Submarine hear the plane impact the water off the Andaman Islands?
On March 13th, “U.S. officials said earlier that they have an “indication” the missing Malaysian Airlines jetliner may have crashed in the Indian Ocean and is moving the USS Kidd to the area to begin searching.”
A sub’s passive sonar station is constantly manned night and day. It consists of a series of arrays of hydrophones that run along the hull on both sides and a computer that can analyze the sounds the sub hears and help classify them for the combat information center on the sub.
This computer can also determine a line of bearing on the contact and estimate the range (and even the depth if submerged) by comparing the sound signatures between hydrophones as they run along the hull. Its accuracy in predicting range decreases depending upon the distance of the sound source and other factors like temperature, depth, salinity and the thermocline layers that these factors combine to create.
A 330 ton airliner hitting the water at 500-600 kts. would sound like a gigantic explosion underwater. And I mean gigantic, roughly 4,500 lbs of TNT going off and exerting a force of 20,000 psi on the water at the impact area. This would result in a giant over-pressure condition in the water that would emanate out as a shock wave (in contrast, the big depth charge explosions in WWII movies were only 300lb charges). It would have a huge sound signature that would travel tens, if not hundreds, of miles, depending upon conditions.
If the sonar operator heard such a sound, they would give it a contact number and log it. At intervals during the day and night, the submarine un-spools an ultra-high frequency antenna buoy and transmits a micro-burst of radio energy to a Sat, which gives the subs position, course, heading, crew emails and various situation reports that would include contacts of interest or unusual occurrences that they think they should phone in. A large underwater explosion would probably qualify as an unusual occurrence.
Tell the time and place you heard the noise and you’ve got a good idea of that sub’s position. We can assume from the time the ACARS pings were being logged that this would have been early daylight of March 8th. That “indication” was considered so credible that the Navy diverted the USS Kidd to the area at high speed to investigate an area that was probably more narrowed down for it by the Pentagon.
So..... did it crash, is it in Diego, or did those pesky feckin aliens take them??
Imagine all that anal probing going on right now....
